The royal blue tube contains the additive lithium heparin which is used to prevent clotting by inhibiting the coagulation process. It is often used in chemistry tests that require plasma samples as it does not interfere with most of the analytes being measured.
A royal blue or lavender tube is typically used for lead blood tests. These tubes contain an additive that helps preserve the stability of lead in the sample during transportation and analysis.
A green-top tube containing lithium heparin or a royal blue-top tube containing no additive is typically used for magnesium tests. The specific tube type may vary depending on the laboratory's preferences.
The tube color commonly used for trace metal analysis is typically royal blue. Royal blue tubes typically contain heparin as an anticoagulant and are used for collecting plasma samples for trace metal analysis.
Calcium is bound by the tube additive ethylenediaminetetraacetic acid (EDTA) during sample collection to prevent coagulation and preserve the integrity of the sample for testing.
The recommended tube for calcium level testing is a lavender or royal blue top tube, as these tubes contain additives that preserve calcium levels effectively. It is important to follow the specific instructions provided by the laboratory where the testing will be conducted.
A royal blue or lavender tube is typically used for lead blood tests. These tubes contain an additive that helps preserve the stability of lead in the sample during transportation and analysis.
A green-top tube containing lithium heparin or a royal blue-top tube containing no additive is typically used for magnesium tests. The specific tube type may vary depending on the laboratory's preferences.
The tube color commonly used for trace metal analysis is typically royal blue. Royal blue tubes typically contain heparin as an anticoagulant and are used for collecting plasma samples for trace metal analysis.
Calcium is bound by the tube additive ethylenediaminetetraacetic acid (EDTA) during sample collection to prevent coagulation and preserve the integrity of the sample for testing.
A royal blue or navy blue tube with no anticoagulant is typically used for lead testing.
The recommended tube for calcium level testing is a lavender or royal blue top tube, as these tubes contain additives that preserve calcium levels effectively. It is important to follow the specific instructions provided by the laboratory where the testing will be conducted.
Light blue tube with sodium citrate additive is used for bleeding and coagulation studies as it helps to prevent blood from clotting by binding calcium.
For measuring parathyroid hormone (PTH) levels, a lavender or royal blue top tube is usually used for blood collection. These tubes contain the necessary additives to preserve the sample for accurate testing.
An HIV test is done in either an SST or red-top tube. It is NOT done in a royal blue tube. An HIV test submitted in a royal blue tube will be rejected.
A lavender or royal blue tube is typically used for collecting a TIBC (total iron-binding capacity) test.
The dark blue tube is typically used for trace element testing, including tests for metals like lead, zinc, and copper. It is often associated with the royal blue tube, which is also used for trace metal analysis but may contain different additives depending on the specific test required. Both tubes are designed to minimize contamination and ensure accurate results for trace element measurements.
A grey tube typically contains blood samples that are collected for laboratory testing. The grey top tube contains an additive called sodium fluoride and potassium oxalate, which are used to preserve glucose levels in the blood sample.
